BACKING-SHEET FOR TYPE-WRITERS.

Patented Nov. 24,1914.

' Application filed October 6, 1910. Serial No. 585,697.

ful Improvements in Backing-Sheets for Type-\Vriters, of which the following is a specification.

It is often desirable to make a number of carbon copies simultaneously on a typewriter plurality of sheets of writing paper and carbon paper simultaneously in the machine and keeping them in register. This is especially so when the sheets are wide, such as the manifests and way bills commonly used in railway freight business.

The present invention relates to an improved backing sheet to facilitate the handling of a plurality ofsheets of writing paper and carbon paper.

The invention will be described in connection with the accompanying drawing, in which,

Figure 1 is a side or edge view of the backing sheet embodying the present invention, together with a plurality of sheets inserted therein, the whole being in condition to insert in the typewriting machine; Fig.

2 is a similar view illustrating the manner of-inserting the sheets in the backing, the flap being raised and the sheets loosely ar ranged under it; Fig: 3 is a plan view of the backing sheet and contents shown in Fig. 1; Fig. 4 shows the manner of inserting the backing sheet in a typewriter.

Referring to the drawing, A indicates the backing sheet which is preferably a sheet of plain, stout, tough paper, and B- indicates 'the flap which covers the forward edges of the sheets to be written upon and the interleaved carbon sheets. The flap B may be made of the same material as the backing sheet.

of the backing sheet, that is, the end which is first inserted in the machine, as illustrated in Fig. 3, The forward margin 10 of the flap strip is pasted or otherwise secured to the backing sheet at some little distance from and parallel with the forward end 11 thereof. The strip is adapted to hinge on a line 12 adjacent to the pasted portion, so

that its free portion 13 may be raised to re-- ceive the writing sheets, as shown in Fig.2

The flap B extends across the forward-end and then folded down upon the forward I edges of these sheets, as shown in Fig. 1.

In the drawing 14 indicates the sheets to be written upon and 15 the interleaved sheets of carbon paper.

The advantages of my invention are its cheapness and simplicity, the ease with which the backing sheet and contents can be inserted in the machine and the fact that it holds the writing sheets and carbon sheets in perfect register. The backing sheet loaded with the required writing and carbon sheets may be termed a pack. It will be seen that the forward edge of the pack is of single thickness which is readily passed between and securely gripped by the-platen and feed rollers, then follows the double thickness consisting of the backing and the pasted strip 10, and finally the flap 13 with the contents of the pack. The advance edge 11 and the pasted part 10 of the pack serve to draw the pack into the typewriter carriage and around the platen very effectively and the flap 13 holds all of the sheets in register until they are all securely gripped by the feed rollers, after which the feed rollers keep them in register during the writing.

It will be evident that my improved backing sheet may be constructed of tough paper or other suitable fabric and that the flap substantially the same characteristics. The

flap should be of material which may be frequently bent' without breaking and which will tend to always spring down into substantial parallelism withthe backing sheet .as shown in Fig. 1. It will'also be evident that the margin 10 of the flap may be in some instances connected to the backing sheet by stitching or stapling, or otherwise, instead of by pasting, although the latter method is preferred on account of its simplicity and cheapness and the fact that it adds practically nothing to the thicln'iess of the backing and flap.

Having described my invention what I claim and desire to secure by Letters Patent is,

A backing sheet for holding writing and carbon sheets and consisting of a sheet and a I strip substantially parallel with and close to but spaced from the-forward end of the sheet, the strip being narrow so as to cover but a relatively small part of the space bemammal tween fine forward enc'l reef enls of the sheeif In testimony whereof I afix my signature sand having its fol-Ward merginfrsecuredi m in presence of two Witnesses. t e sheet midi its rear margin ee t0 pre- I vide a, flap, the free edge of the flep thus ex- JOHN D HAVEN tending toward the rear end of the sheet, Witnesses: s substantially as and for the purpose de- Jesse W.
